Abstract
Abstract An adjustable coupling device is provided which can be secured to each of two sections of conduit, such as two hoses or pipes, by hand, without the need for employing tools. The coupling device comprises a socket member and a plug member which are adapted to be adjustably positioned with respect to each other as one or both members wear, said plug member being adapted to be removably and adjustably disposed in said socket member. The above plug member includes interior walls which define a bore, and securing means, such as teeth or recessed portions. The socket member comprises a body portion having a bore running therethrough defined by the interior walls thereof, which bore is adapted to receive said plug member in a manner such that the bore of said plug member is in communication with the bore of said socket member, and at least one connecting member attached to said socket member and adapted to engage said securing means of said plug member.

Claim 2
Dependent Claim
447 words
A hand adjustable substantially fluid-tight coupling device comprising, in combination, a socket member and a plug member adapted to be removably disposed in said socket member in a first position to form a substantially fluid-tight seal between said members, said plug member comprising a conical-like member including tapered outer walls, and inner walls, said inner walls defining a bore running through said plug member, and at least two securing means, one of said securing means being disposed closer to a narrow end of said tapered outer walls than the other of said securing means, said socket member comprising a body portion including solid rigid outer walls and tapered inner walls defining a tapered passageway running through said body portion, at least one wear resistant lining disposed between said tapered outer walls of said plug member and said tapered passageway of said socket member, said tapered outer walls of said plug member being adapted to seat in in initial portion of said tapered passageway of said socket member, to define said first position and restricted to said initial position when so seated in that it cannot be moved deeper into the socket member, said plug member and socket member by means of said lining forming a substantially fluid-tight seal between said members, and only after portions of said lining have worn, said plug member being adapted to be repositioned by hand, without the need for use of a tool, with respect to said initial portion of said passageway of said socket member to a second portion of said passageway to define a second position and thereby form, by means of said lining, a substantially fluid-tight seal with said socket member, said socket member further including at least one securing means comprising at least one connecting rod, a portion of which is connected to said body portion of said socket member, said connecting rod being adapted to manually engage at least one of said securing means of said plug member when said plug and socket members are in their first position, and after a portion of said lining has worn and said plug member has been repositioned in said socket member to define said second position, a second of said securing means of said plug member and said connected rod of said socket member are adapted to be manually engaged in a second position relative to each other to retain said plug member in said socket member in substantially fluid-tight engagement, said at least two securing means of said plug member being axially spaced from the wide end of said tapered passageway of said socket member when said plug member and said socket member are in the assembled position.
Claim 3
Dependent Claim
86 words
The coupling device as defined in claim 1 wherein said plug member includes first and second end portions, and said passageway of said socket member includes first and second end sections, whereby when said plug member and socket member are in said first position, said first end portion of said plug member is spaced from said second end section of said socket member, whereby after portions of said lining have worn, said plug member can be moved deeper into said socket member to said second position.
Claim 4
Dependent Claim
215 words
A coupling device as defined in claim 1 wherein said plug member comprises a first tubular end segment tapering outwardly to an intermediate segment and a second end segment, and said socket member comprises said body portion including first and second end portions, and an intermediate portion, said inner walls of said socket member defining a tapered passage running through at least said first end and intermediate portions, the wide end of said tapered passage extending from said first end portion tapering inwardly into said intermediate portion, the first tubular end segment and intermediate segment of said plug member being adapted to seat in said tapered passage of said socket member in said first and second positions to form, by means of said lining, a substantially fluid-tight seal with said socket member, said first tubular end segment of said plug member stopping short of the narrow end of said tapered passage of said socket member when said plug member is disposed in said socket member in said first position, the end of the first tubular end segment of the plug member and the narrow end of the tapered passage of the socket member defining a space into which the plug member can be moved into said second position after portions of the lining have worn.
